Lecanora achroa is a species of crustose lichen in the family Lecanoraceae. It was originally described in 1876 by Finnish botanist William Nylander from specimens collected in Rodrigues, Mauritius.[1] The lichen is found in Australia, New Zealand, Papua New Guinea, and North and South America.[2]

Description[]

Lecanora achroa has a yellowish gray to greenish gray, crustose thallus that lies atop a blackish-brown prothallus. The apothecia are sessile, and disc-shaped, measuring 0.3–0.8 mm (0.01–0.03 in) in diameter, with orange-brown discs. The ascospores are more or less ellipsoid in shape, measuring 10.5–16.5 by 6.5–8.6 μm.[3]

The major secondary compounds found in Lecanora achroa are atranorin, 2'-O-, and usnic acid. Species with a similar morphology include and , since both of them also have small apothecia with orange-brown discs.[3] The Brazilian lichen has morphological and anatomical features that are quite similar to L. achroa, but it differs in secondary chemistry, as it produces neither usnic acid nor 2′-O-methylperlatolic acid.[4]
